The host-side CDC subset driver is binding more specifically
than it should ... only to PXA 210/25x/26x Linux-USB gadgets.

Loosen that restriction to match the gadget driver itself.
This helps various PXA 27x and PXA 3xx devices be happier
when talking to Linux hosts; and a few other gadgets too.

Appropriate for -stable ... behaves like a protocol bug.

David this doesn't even compile:

  CC [M]  drivers/net/usb/cdc_subset.o
drivers/net/usb/cdc_subset.c:313:32: error: macro "USB_DEVICE_VER" requires 4 arguments, but only 2 given
drivers/net/usb/cdc_subset.c:313: error: 'USB_DEVICE_VER' undeclared here (not in a function)

There is absolutely no excuse for this, really.

Sorry, my bad.  Fixed in the followup.

Sure there is:  sent it out too soon, before the compile test!
